DI SPLAY RECEPTACLE Filed April 1, 1930 3 Sheets-Sheet 3 Patented Oct. 31, 1933 UNITED STATES PATENT OFFICE 1,932,429 DISPLAY RECEPTACLE Charles P. Wellman, West Medford, Mass. Application April 1, 1930. Serial No. 440,674 4 Glaims. (Cl. 229-32) This invention relates to display receptacles of any suitable foldable material, usually paper or cardboard, and to blanks capable of being formed into such receptacles. When I refer to a"receptacle in this specification I intend to include receptacles of various proportions known as boxes, cartons or trays, and to include receptacles having integral, and receptacles having separable closures, except as otherwise specified.

My invention aims to effect economy in material forming such receptacles, to render such receptacles stronger and more rigid than heretofore,

' particularly through improvement in the fastening or affixing of adjoining sections thereof, and to provide display receptacles which may be manufactured by automatic machinery, my invention providing blanks particularly adapted to cooperate with automatic box-making machinery in being manipulated thereby.

Other objects of my invention will be apparent from the specification and drawings wherein typical species of my invention are explained by way of example.

In the drawings:

Fig. 5 is a perspective view of an open receptacle formed from the blank of Fig. 4';

Fig. 6 is a perspective view of a closed receptacle formed by telescoping two open receptacles such as shown in Fig. 5;

Fig. 7 is a plan view of another blank according to my invention;

Fig. 8- is a plan view of the blank of Fig. 7 with certain parts thereof folded over upon the remainder of the blank preparatory to erecting the blank into a receptacle; and

Fig. 9 is a perspective view of the receptacle formed of the blank of Fig. 7.

Referring to Fig. 2, the open receptacle shown therein is preferably formed of a'single integral sheet of fold'able material, folded to constitute a bottom wall A and side walls B, C, D and. E, one of the side walls, in the present instance that defined by wall-forming sections -13, extending to a less height than the opposite side wall, for the better display of articles contained in the receptacle. By providing one side wall B of less height than the opposite side wall D, a considerable saving of receptacle-forming material is effected. Preferably, as shown in Fig. 2, although not necessarily, the top free edges of the side walls intermediate the high and low side walls slope in part, or as a whole, from the higher side wall to the lower. In receptacles of pro- 35 portions similar to the receptacle of Fig. 2, wherein the high and low side walls are each of less length than the intermediate side walls, the slope of the edges of these intermediate side walls permits an interfitting of the receptacle-forming blanks, and hence a further economy of material. My improved display receptacles present the advantage of capability of being manufactured by automatic box-making machinery which serves to fold various sections of receptacle-forming blanks and fasten them together to form complete receptacles. To this end, two of the side walls of the receptacle, in the present instance the high and low side walls, are formed of mutually fastened integral transverse extensions, preferably three in number, of respective other walls of the receptacle. In order that the receptacle may have continuous unbroken side surfaces suitable to bear advertising or decoration, the side walls thus formed of extensions of other 35 walls preferably contain as their outermost layer a wall-forming section of the shape and size of the wall and entirely covering the outer side surface of the one or more other wall-forming extensions cooperating therewith. Preferably pairs of the smaller wall-forming extensions, for instance extensions G and H in Fig. 2, lie in a common plane and do not overlap.

Referring to Fig. 1 the blank shown therein comprises a single continuous sheet of foldable material divided by fold or score lines of increased flexibility 11, 12, 13, 14, 15, 16, 17 and 18 into a bottom section A, side sections E and C directly joined thereto and wall-forming sections D and B comprising integral extensions of the bottom wall, adapted in the finished receptacle completely to define the high and low side walls respectively. Connecting sections G, H, K and L, comprising extensions of othenwall-forming sections in the present instance of wall-forming sections E and C, are provided, and are adapted in the finished receptacle to connect adjacentside walls.

A preferable manner of economically cutting successive blanks in interfitting relation is particularly illustrated in Fig. 1 wherein another blank indicated in dotted lines is shown as abutting and interfitting with the previously described blank, adjacent blanks lying in reversed position, with one sloping side wall section, C for instance, of one blank abutting a corresponding section C of the adjacent blank as cut from the web of material.

The blank of Fig. 1 is adapted to be operated upon by instrumentalities which fold side wallforming sections transversely with respect to the bottom" section, fold extensions of side wallforming sections transversely with respect to these wall-forming sections, and fasten vertical wall-forming elements together. Preferably prior to. such folding, glue or other adhesive is applied to the wall-forming elements intended to overlap, so that fastening of these elements may be effected by pressure applied thereto in their ultimate positions.

Any suitable closure, integral or separable, may

be employed to close the receptacle of Fig. 2 but preferably such closure takes the form of a similar but slightly larger receptacle adapted to telescope therewith. Referring to Fig. 3 wherein such a closed receptacle is shown, the side wall section C cooperates with the similar section C of the above described open receptacle to form a complete rectangular side wall, these two side wall sections overlapping, as shown.

The blank of Fig. 4 and the receptacles of Figs. 5 and 6 have severalpoints of similarity to the embodiment previously described and shown in Figs. 1 to 3. Accordingly certain fold lines are designated by similar reference numerals, and wall-forming sections are designated by the reference characters applied to the corresponding sections of "the previously described embodiment, with the addition of the letter a. The receptacle of Fig.5, however, differs from that of Fig. 2 in relative proportions of the lengths of the high, low and intermediate walls and in the fact that connecting extensions corresponding generally to extensions G, H, K and L of the previously described embodiment, herein are shown as directly joined to the high and low wall-forming sections rather than to the intermediate wall-forming sections. Thus in the embodiment of Fig. 5 wallforming extensions G H K and L adapted to serve as connecting elements, are directly joined at fold lines of increased flexibility 18, 19, 20 and 21 respectively to the high and low wallforming sections D and B and wall-forming extensions E and C of the size and shape of the ultimately formed intermediate walls are joined to the bottom section A. Preferably the connecting extensions G and H are folded inside of extension C and fastened to its inner face, as shown in Fig. 5, and preferably these extensions G and H are proportioned relative to each other and to the larger extension C to form in the receptacle a, substantially continuous inner thickness of the size of, and completely covered by, extension C By proportioning the relatively smaller extensions, intended to be covered, so that they do not overlap in the finished receptacle, gluing of these extensions to the larger covering extension 0 is facilitated since the combined thickness of portions to be fastened by gluing is uniform throughout the wall, and pressure applied in the gluing operation is uniformly received by the various portions being glued.

The blank of Fig. 4 and receptacle of Fig. 5 illustrate also a preferable corner configuration wherein the two corners of the receptacle defined by the higher side wall thereof are increased in strength by continuing the intermediate or sloping side wall at the same height as the higher side wall for a short distance adjacent thereto. Referring to Fig. 4, extension C which completely defines the sloping side wall has an outer edge portion 25 substantially parallel to the fold line 12 and. hence adapted upon formation of the receptacle to lie at the same horizontal level as the outer edge 26 of the higher side wall, as shown in Fig. 5. When, as in Fig. 5, the outer edge of extension G lies parallel and adjacent to the outer edge of the extension 0*, extension Gr likewise has an edge portion 2'7 extending in the flat blank in prolongation of the edge 26 of section 'D 'and adapted in the receptacle to lie at the same horizontal level as the edge 26 of the higher side wall. 4

The receptacle of Fig. 6, formed by telescoping two receptacles similar to that of Fig. 5, presents the structural advantage derived from the corner construction just described, of having four reinforced vertical corners each including a double thickness of material extending from top to bottom of the receptacle along a distance equal to the length of edge portions 25 and 27.

The blank of Figs. 7 and 8 and the receptacle of Fig. 9 embody numerous features of the previously described embodiments. In these figures, fold lines are designated by the reference numerals applied to similar fold lines in Figs. 1 to 6, and wall-forming sections are designated by the reference characters applied to the corresponding sections of the previously described embodiments, with the addition of the letter Z).

The receptacle of Fig. 9 differs in one respect from that of Fig. 8 by the provision of a turned and reinforced free edge preferably extending substantially continuously around the open side of the receptacle and also in a further change in relative positions of the extensions which form the outer surfaces of the intermediate side walls and completely cover the smaller connecting extensions.

The blank of Fig. I for forming a receptacle of Fig. 9 is provided with bottom, high and low side wall sections A B and D corresponding in general to those of the blank of Fig. 4, and integral extensions G C H K E and L joined thereto, as in the blank of'Fig. 4, the extensions G and K in the blank of Fig. '7 being adapted, however, completely to define the outer faces of the intermediate side walls. In order to trim and reinforce the free edges of the open side of the receptacle, trimming flaps P, Q, R and S are provided and are flexibly related to their conjoined primary wall-forming sections by the provision of fold lines of increased flexibility ,30, 31, 32, and 33. These trimming flaps P, Q, R and S are adapted to be folded over upon and, if desired, affixed to, theadjacent wall sections, as shown in Fig. 8 while the remainder of the blank is in a fiat state.

The partially folded blank of Fig. 8, wherein free edge portions o=f wall-forming sections are of double thickness, may be erected and fastened in a manner similar to the blanks of Figs. 1 and 4 to form the completed receptacle of Fig. 9, the order of folding in this instance, however, being such that the smaller connecting extensions C, H, E and L are folded inside of the larger extensions G and K Preferably in order to form and easily to fasten intermediate walls of maximum strength, the smaller extensions C H", E and L are proportioned with respect to 1 ice each other and to the trimming flaps Q and 'S to form therewith, upon folding into a vertical position, a substantially continuous inner thickness face to face with, and aflixed to, the outer large extensions G and K as describedand claimed in my copending application for patent on Receptacle, filed March 4, 1930, Serial No. 433,010. The receptacle of Fig. 9 may be .closed by any suitable closure, a similar and slightly larger receptacle forming therewith a closed receptacle similar to that of Fig. 6. It will be apparent that any of the receptacles herein described may be closed by a cover of relatively cheap, undecorated material, intended to be discharged when the receptacle is used for display. Particularly in the case of the receptacle of Fig. 9, which is especially strong and rigid due to the provision on the vertical walls of turned and reinforced free edges, such a cover may advantageously be of relatively weaker material.

I claim:

1. Closed receptacle comprising two separately formed interfitted receptacles each formed of an integral sheet of material folded into at least five walls, one of said walls being higher than the opposite wall, the receptacles being interfittedwith the high wall of one receptacle overlapping the low wall of the other receptacle, the high walls of both interfitted receptacles being substantially equal in height.

2. Closed receptacle comprising two separately formed interfitted receptacles each formed of an integral sheet of material folded into five walls,

one of said walls being higher than the opposite wall and the two walls intermediate said high and low walls sloping in height, said receptacles being interfitted with the high wall of one receptacle overlapping the low wall of the other receptacle, the high walls of both interfitted receptacles being substantially equal in height.

3. Closed receptacle comprising two separately formed interfitted receptacles each formed of an integral sheet of material folded into five walls, one of said walls being higher than the opposite wall and the two walls intermediate said high and low walls each having a portion adjacent to said high wall of substantially the same height as the said high wall, and another portion sloping in height, said receptacles being interfitted with the high wall of one receptacle overlapping the low wall of the other receptacle, the high walls of both interfitted receptacles being substantially equal in height.

4. Closed receptacle comprising two separately formed interfitted receptacles, each formed of an integral sheet of material folded into at least five walls, one of theside walls of the bottom receptacle being of greater height than the opposite side wall of said bottom receptacle and the side walls of the bottom receptacle extending between the high and low walls being sloping in height, the top receptacle having a side wall substantially equal in height to the high side wall of the bottom receptacle.
